DF602 Ventilation Rate Monitor

1、 Product Introduction

The principle of combining high-precision thermal sensors and pitot tube pressure measurement is used to measure wind speed. The digital circuit design realizes linear compensation and temperature compensation, ensuring measurement accuracy and wide range ratio under small air volume. The sensor has high stability, and the product has the characteristics of high precision, high resolution, and no zero drift. It can withstand instantaneous high wind speed and high wind pressure. The shell is made of high-temperature resistant anti-corrosion materials, which are stable and reliable for use in harsh environments.

2、 Application scenarios

Widely used in textile, chemical, aviation, power plant, coal mine HVAC, filter pressure drop monitoring, and flue gas treatment; Especially suitable for measuring small wind speeds in areas such as pipeline airflow, variable air volume systems, operating rooms, cleanrooms, biological laboratories, biosafety cabinets, electronics, pharmaceutical environments, etc.
